This decision sets important precedents. Personally, it clarifies how CC images can be handled.

1) "Creative Commoms [sic], CC-BY-SA-2.0″ is sufficient without any URI required. Personally, I will still add it though.

2) Adding the title under the photo but the image attribution on another page is sufficient.

3) To be considered a derivative work, the photo actually has to modified. In this case, it was not.
